Took a look in the garage just now...This one is still a favorite float cooler..wheels,handle, and the original drain plug, are long gone, but it fits my boat very well and keeps stuff cold if you use good ice management. I usually use two coolers for extended trips...one holds food that I'm not going use on the water...one for beverages, lunch, & snacks....
